      Exercise 3: Assign a closure to the `didSelectString` property of `keyboardController` (see KeyboardController.swift):
      
      This closure takes in a string (the string selected from the keyboard).
      If the string is equal to the `DELETE_KEY` constant (see Constants.swift), then call the `deleteLastCharacter` method of `boardController`.
      Else, it should use the `enter` method of `boardController` and pass in the selected string as the argument.
